Voyager 1 Revives Dormant Radio After 40 Years

NASA temporarily lost contact with Voyager 1 in October after the probe unexpectedly switched to a radio frequency it hadn't used since the 1980s. The switch was triggered by the probe's fault-protection system, which activated during a routine command to turn on a heater. NASA regained contact by switching to the S-Band radio, which Voyager 1 had not used since 1981. The incident highlights the challenges of maintaining communication with the nearly 50-year-old probe, which continues to send valuable data from beyond the solar system.

Voyager 1 Revives 1981 Radio for Historic Cosmic Communication

NASA's Voyager 1, the most distant human-made object, recently switched to a radio transmitter it hasn't used since 1981 after a fault protection system was triggered. This occurred when NASA attempted to activate a heater on the spacecraft, leading to communication issues. Engineers reestablished contact using the S-band transmitter, and troubleshooting is ongoing to resolve the problem. Despite its age, Voyager 1 continues to provide valuable data from interstellar space, though its operational life is expected to end by 2025 due to dwindling power.
